To all whom it mag/concern:

Be itknown that I, WILLIAM Hi VH. TRACY,

' a citizen of the United States, and al resident of- Troy, Rensselaer county, State of New structed according to my invention.

`York, have invented certain new and useful Improvementsin Creasing-Machines, of which the following is a specification.

My invention relates to machines for creasing collars and cuffs, and has for its object to provide a simple'and efficient device .of this character.

My invention will be described in detail hereinafter, and the features of novelty will be pointed out in the appended claims.

- Reference is to be had to the accompanying drawings, in whichp Figure 1 is avplan view of a machine con- Fi 2 is a sectional view thereof on the line 2 2g of Fig. 1. Fig. 3 is a sectional view taken on line 3 3 of Fig. 2. Fig.4 is a detail view of v another form of creasing-rollers, and Fig. 5 is a detail view of still-another form of creasingrollers.

lA represents the base of the machine', provided with standards B and B. Attached to these standards B and B is a protectinghood C, secured in osition by screws C.

A driving-shaft Bis j ournaled in bearings E and E .in the standards Band B and has mounted upon it at the end a drivingpulley D, to which power may be applied 1n any suitable manner. v At lits other endy the said shaft D carries a creasing-rollerl D2'. A counter-shaft F, journaled in bearings F and F2 in the standards B and B also carries a creasing-roller G at its one end and has mounted upon it a gear-wheel H, which meshes with a corresponding gear-wheel I on theshaft D.' Zio Th us as power is applied to the pulley'D the driving-shaft D is rotated and through the medium of thegears H and I transmits power to the counter-shaft F, thus rotating `'therewith is a `vided with a roller L" engages the camKi n order to reduce the fric- 5S.

the creasing-rollers D2 and G. l J is a table adapted to receive the material.

A guide J is secured to this table J by means of-a screw J 2. This guide may be of any suitable and well-known form to guide the folded material to the creasing-rollers D2 and-G.

Mounted on the counter-shaft F to rotate cam K, which cooperates with a rocker-arm L. This said rocker-arm is proat theA pointv'where it tion. The rocker-arm L is pivoted at L2 to a lug or projectioh A on the base A and is pro- -understoo vided at its one end with a vstud L3,whi ch en- F2 for the purposes tol be v per end of the casing M. A rod N, provided with an enlargement or through this ca M3 and has its lower end screw threade and screws through the washer M2 and into the bearing E. The object of this construction will description hereinafter.

collar N-, passes appear from the The operation of the device is as'follows:

After the several thicknesses of material have beensewed together to form the`c`ollar in the usual manner the said material is folded or bent over at one end and inserted into the guide J and between the` rollers D2 and G. Power now being applied to revolve the rollers D2 and G, the material will be fed along and creased-as it travels. As the shaft F is revolved thecam K'will cause the Vrocker-arm d'L to vibrate and the roller G to alternately p movetoward and away from the roller D2.

' The object of this intermittent motion is to allow the material being creased to be gradually turned to Aaccommodate the curved or irregular line, upon which the edge of the collar may be cut. If'the rollers were constantly in engagement, it would be impossible to turn the material without buckling` it. In order to prevent the roller D2 from following the roller Gwhen said roller G drops away as the rocker-arm Lis operated by the cam K, the rod ,N is provided, the enlargement or collar N of which engages the cap M3,

and thus limits the downward movement of E and the roller G. It willbe that the bearing F in which the counter-shaft F is journaled, is so arranged as to permit of the limited downward swinging movement of the shaft F and the-roller G when the end of the armLpasses into the cutout portions of the cam K' and, further, that the said shaft F and the'roller G drop down by gravity.

In the form of creasing-rollers shown in Fig. 4 the upper rollerd may be of the same character at the rollerD2 described above, while the lower roller gis a'mutilated rollerthat is, said roller is in feeding or creasing enthe bearing gagement with the roller d intermittently, thus permitting the goods to be turned, as mentioned hereinbefore.

In the structure shown in Fig. 5 both the rollers 1 and 2 are of the mutilated type, engaged intermittently in the same manner and for the same reasons as described with relation to Fig. 4.

It will be understood that when the creasing-rollers shown in either Fig. 4 or Fig. 5 are used the cam K and the rocker-arm L will be omitteol and the bearing F2 will be made stationary. Otherwise the remaining mechanism may be the same as described with respect to Figs. 1, 2, and 3.

I wish it understood that while I have described my invention in connection with collars and cuffs the said machine may be used whenever it is desired to crease material for any purpose.

Various modifications may be made without departing from the nature of my invention.

The intermissions occuring in the feeding movement release the fabric sufficiently to enable it to be turned so that the crease will be curved to correspond to the edge of the article. The guide J simply folds the material preparatory to creasing it and governs the distance of the crease from the edge.

It is unnecessary when using my invention to indicate the crease by a line on the goods or to use any particular care in order to have the crease at a uniform distance from the edge.

I claim as my invention* 1. In a creasing-machine, the combination of two rollers geared together so as to rotate continuously in opposite directions one of said rollers being movable toward and from the other without bringing them out of gear, and means for shifting the movable roller toward and from the other roller at regular intervals as the rollers rotate.

2. In a creasing-machine, the combination of two creasing-rollers permanently geared together, and means for alternately separating the working surfaces of the rollers and again bringing them into cooperative relation at regular intervals during the revolution of the rollers.

3. In a creasing-machine, the combination of two creasing-rollers, one of which is movable toward andv from the other, means for rotating said rollers in opposite directions, and a shifting device, governed by said means, for shifting said movable roller toward and from the other roller.

4. In a creasing-machine, the combination of two creasing-rollers, one of which is movable toward and from the other, means for rotating said rollers in opposite directions, a rocker-arm extending lengthwise of the shaft of the movable roller and connected therewith to shift said roller, and means, located on one of the roller-shafts, for periodically swinging said rocker-arm.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
